Taxonomy of spintronics (a zoo of devices)
02 Nov 2006   Contributor(s):: Dmitri Nikonov, George Bourianoff
The presentation deals with classification of logic devices based on electron spin as a computational variable. Requirements for logic devices are reviewed. Specifically we focus on a) concatenability (output of one device can drive another) and b) the complete set of Boolean operators (NOT, AND,...
